HARROW.

SPECIFICATION forming part of Letters Patent; No. 309,119. dated December 9, 1818 Application filed May 31, 1884.

To aZZ whom it may concern:

Be it known that I, J OHN O. WrLLmns, a citizen of the United States, residing at Anita, in the county of Cass and State of Iowa, have invented certain new and usefulImprovements in Harrows; and-I do declare the following to be at'ull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to harrows; and it consists in the novel parts presently described, constructed, combined, and arranged substantially as will be hereinafter more fully described and claimed.

In the drawings, Figure l is a plan view of my harrow. Fig. 2 is a side view of one end thereof. Figs. 3, at, and5are detail views representing the tooth and holder. Figs. 6 and 7 are detail views of the joint presently de scribed.

The end beams, A, of the harrow are composed of the top bar, A, and the bottom bar, A held together by the clamping devices pres ently described. The beams may beprovided at their opposite ends withhooks A by bonding the ends of the'upper bar, as most clearly shown in Fig. 1. My design in this is to enable the coupling by suitable links of several harrow-sections, so asio form a wide harrow, as will be understood. Theblocks B are placed between the bars A. A and formed with a vertical mortise, B, fitted to receive the liarrowbars, andmade of a depth less than the vertical height of said har'rowdm-rs. These mortises are preferably made from the under side of the block; but may, when so desired, be formed from its upper side without involving a departure from the broad principles of my improvement. I also provide these blocks with side grooves, 15 fitted to receive the clamping-bolts O 0, whereby the blocks are held in place and the harrowbars clamped to the front and rear end beams. Instead of having the bottom bar, A extended entirely across the ends of the harrow,it maybe cutoii on opposite sides of the lnortised blocks, sufficient length being provided for the passage of y the clamping-bolts. The harrow-bars D are (No model.)

set vertically cdgewise and within the mortise l3, and when the bolts Gare tightenedthe bars D are clamped firmly to the end beams. By loosening the bolts the bars may be adjusted longitudinally through the mortised blocks, as desired. It will be seen that I employ one of these joint-blocks at each end, of each of the harrow-bars. The bars D are set vertically edgewise, and secured to the end beamsin the manner before described. I bend the bars D to form the end wings, D D, and the intermediate wing, 1)", both said wings being set at an angle to the end beams and to each other. By this arrangement I secure such a disposition of the teeth that the width of the harrow will be thoroughly worked in the operation of the device. The braces E are secured at one end to the harrow bars at the angle of wings D I), and extend thence to the end beams, and are secured theretoand preferably extended in advance of said beams, and bent to form the hooks E, to which the draft may be coupled. Icallthese hooksth'e draft-hooks, andthey are provided at both ends of the harrow, so it may be drawn in either direction, as desired. lit will be noticed that thesebraces areseeured on the bars 1) on the side opposite that to which the end wings are inclined, and I consequently only employ one on each of the extreme side bars. The number of bars D may be increased at will; but ordinarilylfind three a desirable number, and when a wider harrow is wished for several sections should be connected, as before indicated. By setting the harrow-bars vertically cdgewise it will be noticed they are greatly strengthened. against bending in a vertical. plane, and a lateral springing is provided for, which renders the harrow easy-going and the draft lighter, as will be appreciated. This lateral springing is greatly enhanced by bending the harrow-bars as shown and described, and it is for this and other purposes before described I prefer to so bend them. The teeth are secured on and adjustablealongthese bars pret'erablyin the manner presently described. The tooth-holder F is made open on one side, and has formed in its edge walls from said open side slots, F, fitted to the side of the holder. A clampingbar, F extends across this open side of the holder, and on the opposite side of the harrowbar,and the bolts F F" are passed transversely through the said clamping-bar and the holder, and when these bolts are tightened theholder and tooth G are secured firmly to the harrowbar. By loosening the bolts the holder and tooth may be adjusted along the harrow-bar to any desired point, as will be understood from Figs. 1 and 2. The tooth G is bent at its upper end to form the right-angled arm G. in operation this arm G extends over and rests on the top of the harrow-bar, and bears on its under side against said bar, and on its upperside against the rounded crown F of the holder, forming a pivot on which the tooth may be turned so as to bring it against the vertical side F or the inclined side F of the holder, according as it is desired tohave astraight or inclined toothed harrow. The harrow, it will be understood is drawn from one end when desired tohave a straight tooth, and from the other end when-it is desired to have the teeth inclined.

My harrow is simple in construction, effective in operation, and can be made at slight cost.

Heretofore barrow-teeth have been formed with rightangled arms at their upper ends, serving as journals on which the teeth maybe turned toadj ust them into a straight or i n cl i ned position against straight orinclined walls suitably formed in the holders, and this I do not broadly claim as my invention; but,

Having thus described myinvention, whatI claim, and desire to secure by Letters Patent,

1. The combination of the harrow-bars, the end beam having upper and lower bars, the joint-blocks inortised vertically to receive the harrow-bars, and provided in their opposite sides with grooves, and the clamping-bolts fitting into said grooves and connecting the bars of the beam, substantially as set forth.

2. The combination,with thcdouble-barred end beams and the barrow-bars, of the jointblocks provided with vertical mortises fitted to the barrow-bars, and with verticalboltgrooves on its opposite sides, substantially as set forth.

3. In a harrow, the combination of the harrow-bars, the holder having straight and inclined walls, and provided in one side with a mortise, F, fitted to the bar, and having its crown extended laterally over said mortise, and the tooth held in said holder and having its upper end bent laterally, and extended and bearing between the top of the bar and the crown of the holder, substantially as set forth.

4. The combination of the bar, the holder secured alongside the bar and formed with a straight and an inclined wall, and having its crown projected above the bar, and adapted on the under side of said crown to serve as a bearing for the arm of the tooth, and the tooth held in the holder, and having its upper end bent, formingaright-angled arm extended and bearing between the upper side of the bar and the under side of the crown, substantially as set forth.

5. In a harro\v,thehereindescribed holder, provided with a straight and an inclined wall, and having in one side a mortise, F, fitted to receive the harrowbar, and having its upper side or crown, F, adapted on its under side to serve as a bearing for the tooth-arm, and 6X- tended laterally over the mortise F, substantially as set forth.

6. The harrow, substantially as herein described, consisting of the bars D, setvertically edgewise, bent to form the intermediate and end wings, 1) l), the tooth-holders F,pr0- vided with a mortise, F, fitted to the bars D, and secured thereaga-inst, and having crown F, extended laterally over the bars, the tooth G, secured in the holder and having arm G extended and bearing between the crown F and the top of the bars, the end bearing, A, consisting of bars A A the block B, placed between said bars A A and provided with mortise B, fitted to receive the bags D, and edge grooves 13*, and the clamping-bolts C 0, all arranged and combined substantially as set forth.

x In testimony whereof I afiix my signature in presence of two witnesses.
